Answer:
substitution method
x = 7
y = 2
Step-by-step explanation:
2x - 2y = 10
x = 7
substitute for x:
2(7) - 2y = 10
14 - 2y = 10
subtract 14 from each side of the equation:
-2y = -4
divide both sides by -2:
y = 2
There's an infinite number of solutions. here's a few.
1+-9=-8
2+-10=-8
3+-11=-8
4+-12=-8
5+-13=-8
6+-14=-8
Answer:
When x=1/2, y=28/3
when x =0, y=9
Equation is y=2/3 x + 9
Step-by-step explanation:
First lets convert them to fractions to make it easier. Also put them in order.
X Y
0
1/2
3/4 19/2
1 29/3
6/5 49/5
You can find the slope since we know 2 points.
(3/4, 19/2) and (6/5, 49/5)
m=3/10 / 9/20
m=2/3
y=2/3 x + b
Lets plug in x and y points to find the y-int
19/2=2/3(3/4) + b
b=9
Therefore y=2/3 x + 9
When x=1/2, y=28/3
when x =0, y=9
